Constant Volume System Controls
Remote Panel w/o NSB—BAYSENS110*
This electronic sensor features four system switch settings
(Heat, Cool, Auto, and Off) and two fan settings (On and
Auto) with four system status LED's. It is a manual or
automatic changeover control with dual setpoint
capability. It can be used with a remote zone sensor
BAYSENS077*. Refer to Table 34, p. 85 for the
Temperature vs. Resistance coefficient.
Constant Volume Zone Panel -BAYSENS108*
This electronic sensor features four system switch settings
(Heat, Cool, Auto, and Off) and two fan settings (On and
Auto). It is a manual or automatic changeover control with
dual setpoint capability.
Variable Air Volume System Controls
VAV Changeover Contacts
The changeover input is used with modulating gas heat,
electric heat, or hydronic heat. When the contacts are
closed, the unit will control to the discharge heating
setpoint. Refer to the unit wiring diagram for the field
connection terminals in the unit control panel.The switch
must be rated at 12 ma @ 24 VDC minimum.

Remote Human Interface Module
The remote Human Interface module enables the operator
to set or modify the operating parameters of the unit using
a 16 key keypad and to view the operating status of the unit
on the 2 line, 40 character LCD screen without leaving the
building. However, the Remote Human Interface module
can not be used to perform any service functions.
One remote panel is designed to monitor and control up to
four units providing each of the units are equipped with an
IPCB module. Use the installation instructions that
shipped with the module to install it, and the appropriate
illustrations beginning with Figure 57, p. 87 to connect it to
the unit.
Remote Panel w/ NSB -BAYSENS119*
This 7 day programmable sensor features four periods for
Occupied\Unoccupied programming per day. Either one
or all four periods can be programmed. If the power is
interrupted, the program is retained in permanent
memory. If power is off longer than 2 hours, only the clock
and day may have to be reset.
The front panel allows selection of Occupied/Unoccupied
periods with two temperature inputs (Cooling Supply Air
Temperature and Heating Warm-up temperature) per
occupied period.
The occupied cooling setpoint ranges between 40 and
80°F.The warm-up setpoint ranges between 50 and 90°F
with a 2 degree deadband.The Unoccupied cooling
setpoint ranges between 45 and 98°F.The heating setpoint
ranges between 43 and 96°F.
The liquid crystal display (LCD) displays zonetemperature,
temperature setpoints, week day, time, and operational
mode symbols.The DIP switches on the subbase are used
to enable or disable applicable functions, i.e.; Morning
warm-up, economizer minimum position override during
unoccupied status, heat installed, remote zone
temperature sensor, 12/24 hour time display, and daytime
warm-up. Refer to Table 34, p. 85 for the Temperature vs.
Resistance coefficient. During an occupied period, an
auxiliary relay rated for 1.25 amps @ 30 volts AC with one
set of single pole double throw contacts is activated.
Remote Zone Sensor (BAYSENS073*)
This electronic analog sensor features remote zone
sensing and timed override with override cancellation. It is
used when the RTM has been programmed as the source
for zone temperature control. Refer to Table 34, p. 85 for
theTemperature vs. Resistance coefficient.
Remote Zone Sensor (BAYSENS074*)
This electronic analog sensor features single setpoint
capability and timed override with override cancellation. It
is used with aTrane Integrated Comfort
TM
system. Refer to
Table 34, p. 85 for theTemperature vs. Resistance
coefficient.
Remote Zone Sensor (BAYSENS016*)
This bullet type analogTemperature sensor can be used
for; outside air (ambient) sensing, return air temperature
sensing, supply air temperature sensing, remote
temperature sensing (uncovered), morning warm-up
temperature sensing, and for VAV zone reset. Wiring
procedures vary according to the particular application
and equipment involved. When this sensor is wired to a
BAYSENS119* Remote Panel, wiring must be 18 AWG
ShieldedTwisted Pair (Belden 8760 or equivalent). Refer to
Table 34, p. 85 for theTemperature vs. Resistance
coefficient.
Remote Zone Sensor (BAYSENS077*)
This electronic analog sensor can be used with
BAYSENS119* or 021* Remote Panels.When this sensor is
wired to a BAYSENS119* Remote Panel, wiring must be 18
AWG ShieldedTwisted Pair (Belden 8760 or equivalent).
Refer to the specific Remote Panel for wiring details.
CO2 Sensing—Space or Duct
The CO
2
sensor shall have the ability to monitor space
occupancy levels within the building by measuring the
parts per million of CO
2
in the air. As the CO
2
levels
increase, the outside air damper modulates to meet the
CO
2
space ventilation requirements.
